Gene expression profiling of perinatal or adult regulatory T cells (Tregs)

ABSTRACT: A comparative analysis of gene expression of 3 different experiments; 1. Perinate or adult-tagged GFP+YFP+ and bulk GFP+YFP- Tregs, 2. FL or BM-derived Tregs 3. Perinate or adult thymic Tregs. 1. Foxp3-eGFP-Cre-ERT2 x Rosa26-YFP lineage-reporter mice were injected ip with tamoxifen (4 injections, every third day) between 0-10 (perinate) or 35-45 (adult) days of age, and keep until 8 weeks of age. Perinate or adult-tagged GFP+YFP+ cells and bulk GFP+YFP- were double-sorted. 2. Hematopoietic progenitor cells were isolated from E18.5 fetal liver of CD45.1 congenic mice or from bone marrow of 5 weeks old CD45.2 B6 mice via negative selection of Thy1.2+ cells. The two populations were mixed at a 1:1 ratio, and were iv-transferred into irradiated (1000 rad) Rag-1-KO mice. FL or BM-derived Tregs were double sorted after reconstitution. 3. Foxp3-GFP+ Tregs were double-sorted from perinate (4 days old) or adult (5 weeks old) thymi. RNA from whole samples was amplified, labeled, and hybridized to Affymetrix Mouse Gene 1.0 ST Arrays.

Transcriptional profiling of Bmal1WT and Bmal1KO Tregs

Project description:We isolated visceral adipose tissue (VAT) Tregs from Foxp3.YFP-Cre Bmal1WT or Foxp3.YFP-Cre bmal1flox mice fed a normal lean diet or a high-fat diet. VAT Tregs were also sorted after adoptive transfer. We found that Bmal1KO Tregs are more activated in lean mice, after 4 weeks HFD and after adoptive transfer, but loseVAT Treg signature after 16 weeks of high-fat diet feeding.

RNA-seq analysis of transcriptomes of WT and Foxp3∆2 Treg cells in spleen and LNs

Project description:We performed RNA-seq analysis of Tregs isolated from Foxp3RFP/∆2Foxp3∆CNS1-cre-Thy1.1Rosa26LSL-YFP female mice. CD4+YFP+RFP+ (WT Tregs) and CD4+YFP+RFP- (Foxp3∆2 Tregs) cells were sorted from lymph nodes and spleen to a typical purity of >95% We detected 638 differentially expressed genes (DEGs, FDR < 0.05) between Foxp3∆2 and WT Tregs

Regulatory T cells from colonic lamina propria [array]

Project description:The colonic lamina propria contains a distinct population of Foxp3+ T regulatory cells (Tregs) that modulate responses to commensal microbes. Analysis of gene expression revealed that the transcriptome of colonic Tregs is distinct from splenic and other tissue Tregs. Rorγ and Helios in colonic Tregs mark distinct populations: Rorγ+Helios- or Rorγ-Helios+ Tregs. We uncovered an unanticipated role for Rorγ, a transcription factor generally considered to be antagonistic to Foxp3. Rorγ in colonic Tregs accounts for a small but specific part of the colon-specific Treg signature. (1) Total colonic and splenic Foxp3+ Treg comparison: Lymphocytes were isolated from colonic lamina propria and spleens of Foxp3-ires-GFP mice, where GFP reports Foxp3 expression. TCRb+CD4+GFP+ cells were double sorted into Trizol. (2) Colonic Rorγ+ and Rorγ- Treg comparison: Foxp3-ires-Thy1.1 reporter mice were crossed to Rorc-GFP reporter mice to generate mice that report both Foxp3 and Rorγ expression. Rorγ+Foxp3+ Tregs (TCRb+CD4+Thy1.1+GFP+) and Rorγ-Foxp3+ Tregs (TCRb+CD4+Thy1.1+GFP-) from colonic lamina propria were double sorted into Trizol.To reduce variability and increase cell number, cells from multiple mice were pooled for sorting and at least three replicates were generated for all groups. RNA from 1.5-3.0 x104 cells was amplified, labeled and hybridized to Affymetrix Mouse Gene 1.0 ST Arrays.

Transcriptome data (mRNA and non-coding RNAs) of Bim-deficient Treg cells and aged Treg cells, respectively

Project description:CD4+YFP+ Treg cells were sorted from the peripheral lymph nodes and spleens of Foxp3-Cre mice (8-10-weeks-old), Foxp3-Cre;Bim-fl/fl mice (8-10-weeks-old), or Foxp3-Cre mice (older than 18-months-old), respectively. Detailly, peripheral lymph nodes and spleens were harvested from mice, and grinded into single cells, then the CD4+-T cells were isolated by Mouse CD4 T Lymphocyte Enrichment Set-DM (BD Biosciences, 558131), followed with FACS sorting (SONY Cell Sorter, SH800S) to purify CD4+YFP+ Treg cells with purities >99%. RNA samples were prepared with the miRNeasy Mini Kit (Qiagen, 21704), then reverse transcribed, amplified, labeled (Affymetrix GeneChip pico kit, 703308), and hybridized to Clariom D Arrays, mouse (Affymetrix, 902931).

PDK1 is required for maintenance of CD4+ FoxP3+ regulatory T cell function [heterozygous]

Project description:The goal of this study was to determine the effect of Treg-specific Pdpk1 (PDK1) deletion on the transcriptome of Treg cells in the absence of inflammatory conditions. CD4+ YFP+ Treg cells from spleens and peripheral lymph nodes of Cre-heterozygous Foxp3 YFP-Cre/+ Pdpk1 +/+ (WT) and Foxp3 YFP-Cre/+ Pdpk1 FL/FL (KO) were sorted, RNA was isolated and RNA-seq libraries were constructed and sequenced by Hiseq2500. Note companion data set using hemizygous Cre (induces spontaneous inflammation).

CD4+ YFP+ Treg cells from spleens and peripheral lymph nodes of hemizygous Foxp3 YFP-Cre/0 Pdpk1 +/+ (WT) and Foxp3 YFP-Cre/0 Pdpk1 FL/FL (KO) were sorted, RNA was isolated and RNA-seq libraries were constructed and sequenced by Hiseq2000.

Transcriptional profiling of visceral adipose tissue from Foxp3.YFP-Cre Bmal1WT and Foxp3.YFP-Cre Bmal1KO mice after 16 weeks of high-fat diet

Project description:We profiled the transcriptome of visceral adipose tissue from Foxp3.YFP-Cre Bmal1WT or Foxp3.YFP-Cre bmal1flox mice after 16 weeks of high-fat diet. We found that adipose tissue with Bmal1-deficient Tregs showed an increased enrichment of inflammatory pathways and a loss of metabolic pathways after high-fat diet feeding.

MicroRNA profiling of mouse T regulatory cells (Tregs) reveals miRNA disruption in Tregs leads to uncontrolled autoimmunity

Project description:A new Treg-specific, FoxP3-GFP-hCre BAC transgenic was crossed to a conditional Dicer knock-out mouse strain to analyze the role of microRNAs (miRNA) in the development and function of regulatory T cells (Tregs). Although thymic Tregs developed normally in this setting, the cells showed evidence of altered differentiation and dysfunction in the periphery. Dicer-deficient Treg lineage cells failed to remain stable as a subset of cells down-regulated the Treg-specific transcription factor, FoxP3, while the majority expressed altered levels of multiple genes and proteins (including Neuropilin 1, GITR and CTLA-4) associated with the Treg fingerprint. In fact, a significant percentage of the Treg lineage cells took on a Th memory phenotype including increased levels of CD127, IL-4, and interferon-g. Importantly, Dicer-deficient Tregs lost suppression activity in vivo; the mice rapidly developed fatal systemic autoimmune disease resembling the FoxP3 knockout phenotype. These results support a central role for miRNAs in maintaining the stability of differentiated Treg function in vivo and homeostasis of the adaptive immune system. Experiment Overall Design: Lymph node CD4+YFP+ T cells from FoxP3-GFP-hCre x ROSA26R-YFP Dicerwt/lox (Het) and FoxP3-GFP-hCre x ROSA26R-YFP Dicerlox/lox (KO) mice were isolated by flow cytometry. Triplicate GeneChips were used for each T cell population.
